CHARLES ZIBULSKI, OF MUNICH, BAVARIA, GERMANY.

PIANO-ACTION.

SPECIFICATION formng part of Letters Patent No. .243,481, dated June 28, 1881.

Application filed January 14, 1881.

To all whom it may ooncc'n Be it known that I, CHARLES ZIBULSKI, a subject ot' the King of Bavaria, residing at Munich, in the Kingdom ot' Bavaria, in the German Empire, have invented a new and useful Improvement in Mechanism for Piano- Fortes, of which the following is a specification.

My invention relates to mprovements in nechanism or action for piano-fortes in which a Suspended snapper acts upon the hammer under the axle of the hammer-butt; and the ohjects of my improvements are, first, to provide t'or Vertical or npright piano-fortes the strength of tone requisite for horizontal pianos; and, second, to replace in horizontal pianos the complicated mechanism for repetition. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is an elevation showing the entire mechanism as applied to Vertical piano-fortes. Fig. 2 shows the mechanism as applied to horizontal pianos.

Similar letters represent similar paris in :nl the figures.

The pnshing-plate a is attached to the key w in the usual manner. The pnsher or jack b is Suspended from the snappcr c, which is fixed to the frame m by means of the t'nlcrum d. By tonching the key a; the pnsher Z), and therewith the snapper c, is raised and turned sidewise. This motion is transferred to the end ot' the hammer-butt e below its fulcrunrf, and thereby the hammer-head z knocks on the string. Behind the hammer-butt e is the catch-block g, which by means of a bent piece of wire is attached to the cross-piece h of the lever i.

(No model.)

The liftng of the damper uis etfected in the following manner: The lever i, which rests npon the pnshing-plate a, bears on its upper end the cross-piece h. When the after end of the key x is raised the lever i and the crosspicce h are likewise raised. On the end of the cross-piece h the wire is attached,wh1ch moves the lever 0, and thereby draws hack the danper a from the string. The upper end of rod a is screw-threaded and enters a correspondingly screw-tapped block, o which is hinged or swiveied to levcr 0. The said rod may he scrcwed in or ont of said block to compensate for wear, bending, or changes due to raised or lowered temperature.

The modification forhorizontal pia-nos shown in Fg. 2 ditfers only in the position of the parts b and c, which in this case are connected together at an an gle.

I am aware that prior to my invention mechanism oraction for piano-fortes has been made with suspended pushers, and therefore I do not claim this combination, broadly; but

What I claim as my invention, and desire to secnre by Letters Patent, is-

l. In a pianoforte action, the comhination of the pnsher Z and the snapper c with the ham mer-bntt e and the hammer fulcrum-barf, all constrcted and arranged to operate substantially as and t'or the purpose set forth.

2. In a piano-t`0rte action, the conbination of the pusher Z and the snzpper c with the hanmer-butt e, the hammer fulcrum-har f, pushing-plate a, lover "i, cross-piece and catch-block g, substantially as set forth.
